Abstract
The light emitted from a warning display unit 16 is passed through a front glass 18 formed at the opening of a dash board 17 and a semi-permeable combiner 12 having a first polarizing plate 12 b in this order so that it is guided to a driver's view point I. A second polarizing plate having the same polarizing direction as that of the first polarizing plate 12 b is formed on the surface of the front glass 18 . In this configuration, the wash-out in the warning display unit, i.e. a light emitting source, arranged behind a combiner can be prevented and visual recognition of the light emitting source can be improved.
